I put 140 rounds through my brand new (just picked it up yesterday evening). Combination of Winchester white box and American Eagle 115 grain.

Really fun to shoot this gun. This is the first handgun that I have bought and am really pleased with it so far. Only 1 FTF out of 140 which I don't think is bad for a brand new gun (but what do I know ) My wife even emptied 2 mags. Grip is a little thick for her hands so we will have to find her something else, but she enjoyed it too.

We found the same thing with my wife and the CPX-2, the grip was a little wide for her. I ended up getting her a Ruger LCP 9's which is thinner, but she is having trouble unlocking the slide on it because of the small lock button.

Went to the local range and put another 100 rounds through the CPX-2. They had AE ammo on sale so I went ahead and used that. Had 1 FTE (the first) and 6 FTF. I had several FTF on the last box of AE. so I guess AE ammo is not what to use on my CPX...

Have not yet tried any defence ammo..wanted to get proficient aiming before I spend the money on some defence ammo.

Your Witness-P probably functions very well with WWB and AE (and everything else).Your particular CPX may cycle more reliably with shorter ammo.Remingtion UMC L9MM3 115gr is about .040" shorter overall.It's worth a try, if only to help regain some confidence. hth

That Blazer Brass is a fairly long cartridge, too. See the link in my signature.Maybe call sccy, and explain the FTFeeds with WWB, AE, BB, but no failures with UMC.They might send you a couple new magazines.

Try some Speer Lawman 147gr Flat Nose.It has a shorter cartridge length, and noticeably milder recoil in a cpx.But of course, the nicer the nice, the higher the price.

Remington 115 gr UMC FMJ - 60 rounds - no issuesAE 124 gr FMJ - inserted the clip, racked the slide -- and it didn't feed. Had to tap the slide to get it in - out of the first clip 4 ftf and at least 2 "delayed" feeds. It fed but there was a slight delay before it did.WWB 124 gr fmj - 2 clips - 5 ftf and several of the delayed feeds. One fte

I had changed the base plate of one of the magazines so I could differentiate between the two. It does not seem to be a mag issue as I rotated the ammo between the two clips. No issues at all with the shorter remington ammo.

So I guess the shorter ammo is the way to go with my CPX-2.

I also used the blue locktite on both the pins. I don't know if I didn't get enough on the front pin as it still walked out some. I'll pull it and put some more on before the next shooting session. I am also going to contact SCCY about the pin.

I also tried to convince myself that shorter ammo "only" was ok, until the frame cracked.And when it returned with a new frame, I discovered the temporary wooden shims bs.There are not many uses for an unreliable firearm. Call sccy. Let us know. Good luck.

Keep in mind that the aluminum receiver is mounted in the polymer frame completely independent of the magazine. If the loose frame pins are allowing the receiver to move backward within the frame during recoil, the chambered round draws closer to the next round in the magazine, causing feed failures, or what I've called extraction interference, with longer ammo. Shorter ammo works because the receiver doesn't move that far back.
